2 Claims.

This invention relates to a new and useful improvement in yarn treating apparatus, the novel features of which will be best understood from the following description and the annexed 6 drawings, in which I have shown a selected embodiment of the invention and in which:

Fig. 1 is a vertical view, partly in section and partly in elevation and with other parts broken away, showing a drying apparatus for yarn pack- 10 ages;

Fig. 2 is a plan view of the structure appearing in Fig. 1, parts being broken away;

Fig. 3 is a vertical sectional view on a greatly enlarged scale through the upper end of one of 15 the stacks of yarn packages;

Fig. 4 is a section on the line H of Fig. 3.

The apparatus shown' herein is one designed primarily for use in drying yarn, and will be described in connection with such an operation, a1-

20 though it is to be understood that the apparatus may be used for other purposes for which it is suitable. For the sake of convenience, I shall use the term yarn in referring to the material being treated, that term being used in a broad 25 sense to include not only what is technically known as yarn, but also what is technically known as thread.

Referring first to Figs. 1 and 2 I have shown therein a suitable base I upon which is supported 30 an air chamber 2 to which hot air may be supplied through a duct 3. While, for the sake of convenience, I shall refer to hot air as the drying or treating fluid, it is to be understood that by so doing I do not intend to limit myself to 35 that particular fluid. The top 4 of the chamber 2, in turn, forms a base upon which are supported a plurality of vertically extending perforated pipes 5 having their lower ends extending through the base 4 and secured to that base. In the 40 present instance, the securing of the pipes to the base is done by fastening on the under side of the base, as by welding, a plurality of plates Ii having threaded apertures registering with 'apertures in the base 4. The pipes may then be 45 threaded into engagement with the threads on the wall of the aperture in the plate and the aperture in the base, if that aperture is also threaded. The lower end of each pipe is, of course, open sothat hot air from the chamber 2 may enter the pipes and pass upwardly therethrough and out through the perforation 8 therein.

Each pipe 5 has mounted thereon a stack of yarnpackages I, here shown as in the form of so-called cheeses, this form being commonly used in the art. Each package or cheese is provided with a centrally disposed opening in which is a'compressible core 8, here shown as formed of a spiral coil, this type being well known in the art and needing no further description.

In the apparatus shown, I have provided a basket or container for the yarn packages, this basket being shown as in the form of a cylinder 9 having a bottom Iii provided with holes through which the pipes 5 extend. As described above, the pipes 5 are secured in fixed position on the base 4, and the arrangement of holes in the bottom l corresponds to the arrangement of pipes so that the basket may be put in place and removed by sliding along the pipes.

In operation, the basket is first placed in position by sliding downwardly over the pipes, and then the stacks of cheeses are slid over the pipes until they reach such a height as to extend a material distance beyond the upper ends of the pipes, the pipes normally being approximately of equal length. In order to compress the cheeses to a uniform density, they are pressed down upon the pipes, this being achieved by means of a cover it bearing against plates l2 interposed between the cover and the tops of the respective stacks. In order to center each plate I! and at the same time to permit proper circulation of the hot air, I leave the upper end ii of each pipe open and provide each plate II with a stem ll of materially smaller diameter or cross-sectional area than the inside of the pipe, so that the stem can be inserted in the pipe.

I provide suitable spacers to guide the stem in its telescoping contact with the pipe, and arrange these spacers so that they will not interefere with the free flow of fluid. In the form-indicated, these spacers are projections l formed upon the rod which comprises the stem It. This rod may be conveniently threaded into the plate l2, as shown, and the projections l5 may be formed in any suitable manner, for example by deposit of weld metal upon the rod. It will be seen that the projections are spaced apart both lengthwise of the stem and circumferentially thereof, so that a free flow of air may be had between the pipe and the stem clear to and through the open end l3 of the pipe.

The cover ll may be pressed downwardly by means of hand-wheels i6 threaded upon rods I1, 50 supported upon vertically extending posts i8. In the form shown, there are four such posts equally spaced about the periphery of the basket and cover, and two opposite rods [1 are rigidly connected to or integral with their post l8, as shown 55 pivoted at iii to their post iii. The hand-wheels engage spaced ears it on the cover, and when pressure is exerted by the hand-wheels upon the plates 92, the yarn packages or cheeses will be compressed, the amount of pressure being controlled at will. By making certain of the rods i'fl rigid with their posts and thus rigid with the base, I insure that the cover it will not move horizontally to any great extent, while the pivotal connection of others of the rods it to their sup ports facilitates removal of the cover.

After the cover is secured in place, hot air or other fluid is admitted to the chamber 2 through the duct 3, the air being under sufiicient pressure to pass through the pipes 5 and out through the perforations and thence through the yarn packages, it being understood that the cores of the packages are porous, as is well known in the art. It will be noted that the wall 9 of the basket is provided with a multiplicity of perforations 23 so that the air, after passing through the packages, may escape from the basket and some of it may pass between the upper edge of the wall and the cover.

After treatment has been completed, the cover may be removed and then the basket may he lifted by any suitable hoisting apparatus, not shown, this lifting of the basket stripping the yarn packages from the pipes. Such hoisting apparatus may include hooks adapted to engage handles The packages may then be removed from the basket and the basket returned to the apparatus for further use in treatment oi another hatch oi packages.

While I have shown the invention as embodied apropos in a specific form, it is to be understood that various changes in details may be made without departing from the scope of the invention, and I therefore do not intend to limit myseli except by the appended claims.

I claim:

1: A yarn-treating apparatus comprising a perforated pipe having one end thereof open and upon which yarn packages may be stacked, with the pipe disposed in alined openings in said packages and with the top oi the stack extending beyond said open end of the pipe, a plate engaging the top of the stack, a stem secured to said plate and extending within said pipe, said stem being of materially smaller cross-section than the inside oi said pipe, and projections on said stem engaging the inner wall of the pipe and spaced apart lengthwise of the stem and peripherally thereof to permit how of fluid thereloetween.

2. In combination, a base having a plurality of perforated pipes extending therefrom and upon which yarn packages may be stacked, said pipes ending at substantially equal distances from said base, a basket having a bottom provided with holes through which said pipes may extend and having a wall extending generally parallel to said pipes, means for supplying fluid to said pipes, a cover extending over the ends of said pipes but normally out of contact with said basket wail, means to press said cover towards said base to compress the stacks of packages on said pipes, and a plate associated with each of said pipes and disposed between said cover and the adjacent end of the pipe and having a stem extending within the pipe hut spaced from the inner wall thereof.
